Hi
Clicking on the PDF icon to display an invoice open an error message in new browser window. Same for the batch downloading. Here it is (translated from my browser language the best I could):

Deactivating GZip, and the same actions open no error but an _empty_ Administration page.

Your help would be much appreciated.

Config:
VM Invoice (latest)
Joomla 2.5.24
Virtuemart 2.6.6

Hi,

If there's only a white page displayed when you deactivate GZip, it means there's some PHP error encountered. Please either enable displaying errors or check your server's errors log and post the error message reported.
What version of PHP do you use? The latest VM Invoice requires PHP 5.3.

Hi thank you dajo for replying

Page's empty but not white: Attached a screenshot of the empty Administration page we get when clicking on the PDF icon to display an invoice: that is without gzip, Joomla Debug on Maximum & VM Debug: ON
Looks there's only Strict Standards warning.

PHP 5.4.24
VM Invoice (latest)
Joomla 2.5.24
Virtuemart 2.6.6

Please gzip has to be disabled for the component to work?

Thank you for your help.

Hi,

It should work with GZip, I think the main problem is that it doesn't work for you even with GZip disabled, so there's some other issue.
Please post the URL that is displayed in the popup window address bar when you click the PDF icon (you can hide your domain, I just need the part after index.php).

Hi

It feels good to be supported ;)

URL of the popup window opened by clicking on the PDF icon (last column)
/index.php?option=com_vminvoice&controller=invoices&type=invoices&task=pdf&document_type=invoice&cid=4514

And URL when going for invoices batch download:
/index.php?option=com_vminvoice&controller=invoices&type=invoices

Looking forward for your help to solve this issue.

Hi,

The URL is correct. Try disabling the Strict standards error reporting. The problem could be that errors are displayed before correct PDF headers are sent.
